AVR series high-precision automatic AC voltage stabilizer is composed of contact voltage regulator, servo motor, single-chip control system, etc. When the grid voltage is unstable or the load changes, the automatic sampling control circuit sends a signal to drive the servo motor to adjust its The position of the carbon brush of the voltage regulator makes the output voltage of the voltage regulator adjust to the rated value and reach a steady state.
Tech features
With liquid crystal display, overvoltage, overcurrent, overtemperature and other protection functions, long delay and undervoltage protection can be added according to user needs. The device has self-detection capacity and shows its status with LED lamps.All green lamps indicate the regulator normal and the red lamps indicate abnormal.The output power can be showed with a voltmeter.The regulator,with modular design,This regulator consists of three pieces of high-precision regulation boards,and provides the best quality guarantee through TCT automatic testing as well as aging test.
